How to resize a shape with custom ShapeTemplate in ShapeTemplateSelector

[rui]

I use ShapeTemplateSelector to design some different shape,   to resize the shape , I add Thumb in the DataTemplate，it is inefficient

I wish to resize a shape by the diagram‘s ’native behavior  but  the  shape is not resize by the outer rectangle

How to resolve it

Hi Stefan

Thanks for your reply

I solve the problem by resizing event

int the event method  i set the shape's  width or height binding value as the bounds's width or height,the code is as follow

void CustomResizingService_Resizing(object sender, ResizingEventArgs e)
        {
            foreach (var item in _selectedItems)
            {
                var shape = item as RadDiagramShape;
                if (shape == null) continue;
                var squidNode = shape.DataContext as SquidNode;
                squidNode.Squid.Location_x = (int)item.Bounds.X;
                squidNode.Squid.Location_y = (int)item.Bounds.Y;
                squidNode.Squid.Squid_width = item.Bounds.Width;
                squidNode.Squid.Squid_height = Math.Max(item.Bounds.Height, squidNode.MinHeight);  
            }
        }

<Style x:Key="SquidShapeStyle"
           TargetType="telerik:RadDiagramShape">
       <Setter Property="Width"
                Value="{Binding Squid.Squid_width,Mode=TwoWay}" />
        <Setter Property="Height"
                Value="{Binding Squid.Squid_height,Mode=TwoWay}" />

           ...
    </Style>

I think，when resizeing， the shape's width and height  should auto change without above code ，

Did I miss anything important？

Hi Rui,

Thanks for the update.

I cannot confirm the exact cause for this behavior, as there seems to be a customization of which I am not aware. Can you please double check whether there isn't some Margin applied within the customized template, as this is my best guess for the selection rectangle being around the shape. Although the solution you have found might be working as expected, placing the control within a ViewBox, for example, might do the trick out of the box.
